Men around the world hoping to woo Pippa Middleton are unfortunately out of luck; she is reportedly "all but engaged" to boyfriend Alex Louden.

Dubbed "Her Royal Hotness" by the British media, Catherine Middleton's younger sister stole a slice of the limelight during the Royal Wedding, wearing an elegant white Sarah Burton-designed dress which clung to her well fit body and displayed glimpses of cleavage.

On Facebook, several groups have been created, including The Awkward Moment you become a Sex Icon at your Sister's Wedding, which this morning had more than 17,800 members.

Another, the Pippa Middleton Ass Appreciation Society, a page dedicated to Pippa's "fine ass", has this morning more than 112,000 members.

On social networking website Twitter, wedding watchers reportedly nearly crashed the site with mentions of Pippa on Friday night, with many commenting Prince William's brother and best man, Prince Harry, should be the next to walk the aisle.

Prince Harry was noted by some to give Pippa the "glad eye" during the ceremony, and is reported to have leaned over to her during the ceremony and whispered: "You do look very beautiful today, seriously."
But the 27-year-old is spoken for; Pippa has been dating the cricketer-turned-banker Louden for around a year.

"Alex has no reason to fear Harry would turn Pippa's head," a friend told the Mirror. "Harry may be royal, but Alex is upper-crust, rich and good-looking. He's exactly Pippa's type and I don't think even a Prince would be much competition."

While some have accused Pippa of stealing the limelight off her sister by also wearing white - which is unusual for a bridesmaid - others have commented that it shows the bond between the two sisters.

"I think it shows sisterly love to give Pippa such as pretty dress," novelist Christobel Kent said, the Telegraph reported.
